-e: When building for the web player using WWW methods with postData and headers, the headers are partially sent as POST body. This leads to failing validations in e.g. NodeJS/Hapi/Joi.
This problem does only occur on WebPlayer builds, in the editor all is fine as well as when deploying to iOS or Android.

-repro:
--Build the project below or use the webplayer build included.
--run build
---Currently it points to a test script at my site which is also included which just prompts the POST body.
--open browser tools
--go to network section
--examine the header and body of the request
--NOTICE that parts of the header are sent in the body
